A conflict of the soul and my 96 cobra.

1. There's no timing belt on a 4.6L DOHC. Just timing chains. And I've seen them go three times that mileage without having to change them. They don't suddenly snap and wipe out the top end like a timing belt. Unless you know for certain there's a problem, don't concern yourself with it.

2. What makes you think you need new valve springs?

3. Remove the IMRC place and clean them. They carbon up over time. Won't cost you more than a gasket kit. Assuming yours it bad, a remanufactured AIR pump for your car will run you about $150

4. See above post.

It's an older vehicle now and will have older vehicle problems. Your current issues could probably be fixt for well under $500.

That about 1-month of a new car payment.....and you'll have 71-more months of $500 payments after that. Food for thought.
